This formula helps you calculate the statistical significance of the difference between two sample groups.
Mc +n.Ec = Mv - n.Ev n(Ec+Ev)=(Mv - Mc) n=(Mv - Mc)/(Ec+Ev) where M is the mean E is the std error of the mean (ie the std dev/sqrt(sample size)) c is for the control v is for the variant n is the number of std error from the mean between the control and the variant.
You should then calculate the area under the Gaussian curve for -infinity to n, which is 0.5 + area between 0 to n which is erf(n)
